Hello, happy 2023 to all! I want to change my screen 4.3 to 8.4 and I want to purchase the radio with navigation. They offer me the model P05091037AI and I don't know if it has navigation or what module it belongs to. Would someone be so kind as to tell me how I can know which radio is R2 or RB5? Thank you all for the help you can give me, I am from Argentina. Greetings!
